Troitske fire, May 2022 Троїцький район · Troitske

Out · last measured on 8 May 2022

The fire started on 8 May 2022 in Troitske, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 111 hectares from satellite imagery, spread across a single municipality.

It is the 807th largest in Luhansk Oblast since 2016 (of 909 with a page). Number 487 in Ukraine in 2022, of 531.

We have the Copernicus perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

The weather day by day

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke

CAMS · Copernicus

On 9 May 2022 the air beside the fire reached 12 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions

How long did the Troitske fire last?
Copernicus dates it between 8 May 2022 and 8 May 2022: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 111 hectares (1.1 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Troitske (111 ha, 0.1 %).
Did the fire reach a town?
The closest fire to a town centre came within 16.3 km of Troitske. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.
What was the weather like?
During the fire the temperature reached 22.6 °C, humidity dropped to 3 % and gusts hit 20 km/h. The fire danger index (FWI) reached 25, class High.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Ukraine (geoBoundaries). It is not an official report.

Where to verify it

A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Satellite cross-check

Does something look wrong on this page?

This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

Where this data comes from

The perimeter and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Public Domain). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
